In some embodiments, the shell is configured to prevent recursion (e.g., in the event a command to execute the same notebook is selected, the notebook is not executed). In some embodiments, the notebook produces output. Control then passes to 516. In 506, it is determined whether the selected command comprises a local command. In various embodiments, it is determined whether the selected command comprises a local command based on an estimated time to complete the command locally, an estimated processor load to complete the command locally, a data usage, an indication of whether the command comprises a local command, or any other appropriate indication. In the event it is determined that the command does not comprise a local command, control passes to 510. In the event it is determined that the command comprises a local command, control passes to 508. In 508, the command is executed locally (e.g., by the shell). In some embodiments, executing the command locally comprises determining the language that the command is in. In some embodiments, the language that the command is in is determined by the command syntax. In some embodiments, the language that the command is in is determined by an identifier (e.g., “% scala”). In some embodiments, the locally executed notebook command produces output. Control then passes to 516. In 510, it is determined whether the selected command is a cluster command. In various embodiments, it is determined whether the selected command is a cluster command based on an estimated time to complete the command locally, an estimated processor load to complete the command locally, a data usage, an indication of whether the command comprises a cluster command, or any other appropriate indication. In the event it is determined that the command does not comprise a cluster command, control passes to 512. In 512, the command is provided to a cluster for execution. In some embodiments, providing the command to the cluster for execution comprises determining what language the command is in. In some embodiments, the command executed by the cluster produces output. Control then passes to 516. In 514, the command is executed in any appropriate way (e.g., the command comprises a special case and is executed in any way appropriate to the command). In 516, it is determined whether there are more commands. In the event it is determined that there are more commands, control passes to 500. In the event it is determined that there are not more commands, the process ends.
